Researchers at the Guangzhou Institutes of Biomedicine and Health have proudly unveiled their latest project: using cells from human urine to grow new teeth. Pee is, apparently, chock full of potential stem cells that can be converted into the enamel, pulp, and other components of healthy teeth.
While the Guangzhou researchers are excited about their discovery, not everyone is quite as enthused. According to Gizmodo:
The method has its limitations – it involves mouse cells, has a success rate of around 30% and the structures were about one-third of the hardness of human teeth.
So although the “tooth-like structure” contained dental pulp, dentin, enamel space, and enamel organ, they’re in no way at the point of being a viable replacement. Which isn’t really a surprise, considering Professor Chris Mason, a stem cell scientist at the University College London, says that human urine is “probably one of the worst sources” and “you just wouldn’t do it this way.” So not a ringing endorsement
